Magnetism

We live in a sea of waves. With this exciting visual aid, students can explore the unique relationship between the unseen electric and magnetic waves surrounding us. See the difference between wave- length and frequency scales in addition to understanding radio and microwave usage, x-ray, and gamma ray absorption and much more! Accompanied by an explanatory sheet.

by Sara Bernard

The whirring and clicking of homemade machines fills this middle school classroom turned science museum, stacked high with magnet sculptures, spinning plates, and funhouse mirrors. A shop vacuum balances a beach ball on its upward air current; a humidifier, hooked up to an aquarium tank, gurgles out thick, white vapor that students can touch and pour into cups. Two-liter soda bottles, plastic funnels, cast-iron pans, and discarded television sets demonstrate everything from momentum to magnetism in a way that clearly captivates a preteen audience: above the din rises an incessant chorus of "Ooh!"s and "Ahh!"s and the occasional delighted shriek.
